This activity is a simple response time game where the students chase a button, building up and analysing score data as they go. There is a one time “outlier” button that departs from the layout of the other buttons and should take the students by surprise and thus generate a meaningful outlier in the data.
The data can be displayed by a histogram and a box and whiskers plot, giving a good illustration of the relationship between them.
Questions to ask include:
- Look at any identified outliers. Was there anything different about your response on these occasions?
- What do you notice about the difference between the median and the mean?
- Can you relate this difference to the shape of the histogram?
